The Godzilla Sand and Dust Storm generated Traveling Ionospheric Disturbances, influencing space weather and ionospheric CONDITIONS. – Edward, et al. 2024
The article explores the occurrence of Traveling Ionospheric Disturbances (TIDs) over Morocco during the “Godzilla” Sand and Dust Storm (SDS) event, which took place from June 15th to 26th, 2020. This powerful SDS event provided a unique opportunity to study its influence on the ionosphere using Global Navigation Satellite System (GNSS) data. Specifically, the research focuses on analyzing Vertical Total Electron Content (VTEC) data from four GNSS receiver stations spread across Morocco, allowing for precise tracking of ionospheric disturbances over time. To better understand the underlying causes of these disturbances, the study also examines solar wind parameters and geomagnetic indices, both of which play significant roles in ionospheric dynamics. The findings reveal that during the SDS event, the TIDs propagated poleward, driven in part by neutral winds in the upper atmosphere. This suggests that the SDS event was capable of generating atmospheric gravity waves (AGWs), which, in turn, manifested as TIDs. The results highlight a strong connection between SDS events and ionospheric activity, confirming that such storms can serve as significant sources of energy, capable of triggering Medium Scale Traveling Ionospheric Disturbances (MSTIDs). This discovery is important as it establishes a link between terrestrial weather phenomena, like sand and dust storms, and space weather, broadening our understanding of how surface-level events can influence the behavior of the ionosphere. In addition, the study enhances our comprehension of the complex interactions between the Earth’s atmosphere and ionosphere during extreme weather events, shedding light on the mechanisms by which SDS events can influence space weather. These insights are crucial for improving our ability to predict and mitigate the impacts of TIDs on communication systems, satellite operations, and other technologies dependent on stable ionospheric conditions. Overall, the research contributes valuable knowledge to the fields of atmospheric science and space weather, emphasizing the role of SDS events as an underexplored driver of ionospheric disturbances.
How the Study was Conducted
The authors employed Vertical Total Electron Content (VTEC) data from four GNSS (Global Navigation Satellite System) receiver stations located in Morocco. The authors analyzed solar wind parameters and geomagnetic indices to understand the external influences on the ionosphere during the SDS event. The VTEC data was used to identify and track the propagation of TIDs. The researchers looked for patterns and disturbances in the ionospheric electron content that indicated the presence of TIDs. The study correlated the occurrence and characteristics of TIDs with the timing and intensity of the SDS event. They examined how the SDS might have generated atmospheric gravity waves (AGWs), which in turn manifested as TIDs. The authors observed the direction and speed of TID propagation, noting that they moved poleward and were influenced by neutral winds.
What the Authors Found
The study confirmed that the Godzilla SDS event generated TIDs, which were observed as wave-like structures in the Total Electron Content (TEC) data. The TIDs propagated poleward, as indicated by the TEC data from the GNSS receiver stations.
The study also posits that neutral winds played a significant role in the propagation of atmospheric gravity waves (AGWs), which are manifestations of TIDs. The study ruled out geomagnetic activity as a significant factor, attributing the TIDs primarily to the SDS event.
Why is this important?
Understanding Atmospheric Dynamics: The study provides insights into how sand and dust storms (SDS) can influence the ionosphere by generating atmospheric gravity waves (AGWs), which manifest as travelling ionospheric disturbances (TIDs). This helps in understanding the complex interactions between the Earth’s surface events and the upper atmosphere.
Impact on Communication Systems: TIDs can affect radio wave propagation, which is crucial for communication and navigation systems that rely on GNSS signals. By understanding the sources and behavior of TIDs, we can improve the reliability and accuracy of these systems.
Climate and Weather Prediction: The study highlights the role of neutral winds in the propagation of TIDs, which can be important for climate and weather models. Accurate modeling of these disturbances can lead to better predictions of weather patterns and climate changes.
Scientific Knowledge: This research adds to the body of knowledge about ionospheric disturbances and their causes, contributing to the broader field of space weather research. It helps scientists develop more comprehensive models of the ionosphere and its behavior under different conditions.
What the Authors Recommended
- The authors suggest conducting more studies to explore the relationship between SDS events and ionospheric disturbances in different geographical regions and under various atmospheric conditions. This would help in understanding the global impact of such events.
- The authors recommend enhancing the monitoring of SDS events and their effects on the ionosphere using a network of GNSS receiver stations. This would provide more comprehensive data and improve the accuracy of detecting and analyzing TIDs.

In conclusion, the study by Edward et al. (2024) significantly advances our understanding of the complex interplay between terrestrial weather phenomena and space weather. By analyzing the effects of the Godzilla Sand and Dust Storm on the ionosphere, the research highlights how such extreme weather events can generate Traveling Ionospheric Disturbances through atmospheric gravity waves. This underscores the broader impact of surface-level events on space weather and emphasizes the importance of enhancing our predictive capabilities for ionospheric disturbances. The insights gained from this study not only contribute to scientific knowledge but also have practical implications for improving communication systems and refining weather and climate models. Continued research and monitoring will be crucial in developing strategies to mitigate the effects of TIDs and enhance the resilience of technologies reliant on stable ionospheric conditions.
